将字符串与ListViewItem中的ContentView上的label.Text绑定

// 定义视图模型类
public class ViewModel : INotifyPropertyChanged
{
    private string _text;

    public string Text
    {
        get { return _text; }
        set
        {
            if (_text != value)
            {
                _text = value;
                OnPropertyChanged(nameof(Text));
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

// 在XAML中进行数据绑定
<ListView>
    <ListView.ItemTemplate>
        <DataTemplate>
            <ViewCell>
                <ContentView>
                    <Label Text="{Binding Text}" />
                </ContentView>
            </ViewCell>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>
